I am new to CA service desk.Please let me know from where I can learn basic of ca service desk customization such as working with spell code etc.
It will be very helpful if video tutorials are available for the same.
Spell Code is considered out of scope for support so it is generally not documented in the OOTB documentation. However, thanks to a few people in the CA Communities that have been kind enough to give us a crash course on this. See post below:
Where can I find Spel functions documentation?
Thanks to Gutis, many spell method have been documented in this post: SPEL API methods
Note that either if the community will try to help you here you are on your own with spell as mentioned before this is not supported by CA. Wrong spell can dramatically hurt so must always been used as last solution.
Hope this help
